FirstRate 5 (FR5) is a free energy rating software package that simulates the energy efficiency of a proposed new house designs in Australia. FirstRate 5 is developed by Sustainability Victoria, a department of the State Government of Victoria.
FR5 implements the Australian standard Nationwide House Energy Rating System (NatHERS) to assign a star rating which is recognised by the Australian National Construction Code as proof that a house design is energy efficient.
FR5 is one of the official NatHERS Accredited Software packages that can be used by Accredited Assessors to generate official NatHERS Certificates required by Australian planning authorities as part of the Development Application process.
FR5 uses the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Chenath engine to perform the energy calculation engines which is the same engine used by all NatHERS Accredited Software.
FR5 comes with a PDF User Manual which you can open from the main window menu Help -> User Menu. Otherwise the file can be found at C:/Program Files (x86)/FirstRate5-x.x.x/FirstRate5Manual.pdf
There is useful information and links at the FR5 FAQs and page.
The NatHERS website also has useful information at Using NatHERS Accredited Software including the latest Handbook and Technical Note.
